What is the weirdest movie prop you've seen?

You don't have to have personally seen the prop itself, but just the movie it's in (though if you have, somehow, seen the prop itself, bonus points).

This was inspired by the thread about the Mount Rushmore replica from Ritchie Rich. It's just a bizarre thing to be asked to make. Then I was thinking of other, weirder props that had to be made for movies.

My favourite would have to be from the movie Brain Candy, which had a mouse "frozen" in its wheel (according to the movie, it was in a "happiness coma" from taking an anti-depressant). It's just such a weird thing, and to think about what the props department thought when presented with the idea. "We need a catatonic mouse frozen, mid-stride, in its wheel". It's such a simple prop, but man is it weird.
